New Tulsa Interstate (US-412)

[BoulderSooner]

There’s also a spur north of Tonitown it can and likely will tie into. ArDOT already has plans to redo that interchange at I-49. I’d be willing to bet they find a way to expedite this project.

the spur that is north of tonitown (612 ) the next phase (before the east side project that you linked) is on the west side from existing 412 up to the 612 spur ..

Correct I mentioned it because it appears ArDOT has plans to expand that facility even further east at some point.

612 by pass is going to reconnect with 412 right before the lake

Correct which is why I think it’ll tie in with a Siloam Springs Bypass. There’s the airport XNA connector project as well in the area.

i don't think so I think you can expect the main line the new interstate going west from 49 to be 612 until in connects with 412 (around highway 68 and 412 ) then 412 be full interstate for 10 miles or so until it connects to the future siloam bypass some where east of siloam springs ..

Here’s a new article which sheds some light and gives somewhat of a timeline: https://www.4029tv.com/article/bids-...pass/45727996#

and all but the eastern 6 miles or so of this is fully funded and the bids are either already approved or out for bid

Good note but I believe they own the ROW.

I believe ODOT will build it as a free to use freeway and not an extension of the existing turnpike(on the the OK side obviously) but I’m not sure.

It seems a little odd they are shifting this south to the existing 412 near Tontitown, given a few miles west of this they are going to need to then go around Siloam Springs, when it would be basically a strait line west from the existing part built to go past Siloam Springs. Plus anything this saves in new highway miles added, probably gets offset in complications during construction, as the road will likely be kept open while doing upgraded between those two cities.

it is 10 full miles that is a lot of ROW to acquire for one reason

and it is really not that much out of the way

They are acquiring around half of that with the shift down and around, and land they acquire around the existing 412 is probably worth more than farmland north of it.

going south back to 412 costs them about a mile +/- of "extra" ROW "

also that part of the project is actually funded and is starting .. (and is needed now)

The feds have approved this as Interstate-42.

[Mesta Parker]

The extension of AR-612 to US-412 just east of Siloam Springs is under construction with an estimated completion date of Aug '26.

Also construction has started in Catoosa on the US-412, OK-66, I-44 interchange. Estimated completion, summer '26.

Arkansas still hasn’t funded the Siloam bypass though

Have they even chosen a route for it?

[Urbanized]

^^^^^^^^
As mentioned in the graphic, they are looking to convert existing highway alignment into interstate. No new route to be chosen; the route already exists.

I think they are talking about the siloam bypass specifically

[Urbanized]

Ah, makes sense. But wasn’t mentioned in that specific post.

Correct. They are still trying to determine if it will be a north or south bypass.

As a person who has traveled that route on HWY 412 for almost 35 years, come on Northwest Arkansas get it together. You've had years to plan this.

That area has been consistently gaining population (doubled since 1990) and very little has been done on the Arkansas side to divert traffic around Siloam Springs to the east side of Springdale in the last three decades. Almost 600,000 people are in Northwest Arkansas and the area will probably overtake Little Rock's MSA as Walmart and other companies continue to grow.

On the Oklahoma side, the Cherokee Turnpike was authorized in 1987, and opened in 1991 with 35 or so miles.

Ideally this route would go all the way to Harrison linking up just to the west of Harrison and Highway 65, it would then allow a solid route to Branson/Springfield Missouri.

Also new convenient access to that new amusment park they're building out in NE OK.

--being built like 100% for sure.

Topography gets significantly more challenging as you head east of Springdale. I-42 will definitely make that route to Table Rock/Branson easier though.

currently this will end with the springdale bypass ... reconnecting with 412 just west of the lake (east of sonora) ...

seems like it would be pretty easy to upgrade 412 for an additional .. 15 miles or so to just north of huntsville .. but after that you would need significantly more funding ..
